I agree that a rigorous course is more beneficial than enrichment.
The idea of breath and depth is appealing, but I doubt that it is actually accomplished in many situations. Additionally, all children could gain more meaningful understanding through enrichment, but only some need more advanced instruction. The floor should be raised for almost everyone, because to a certain extent, all children live up or down to the expectations that are set for them. I believe that our current educational standards, in general, are too low for most.
